Ever wonder what happens to old subway cars when subway lines upgrade to newer trains? In Beijing at least, the ones used pre-Olympics have been shipped to Sichuan and converted into temporary winter shelters. Ten DK-16 trains, each with six cars, are now in Guangyuan, a city north of Sichuan's capital Chengdu.

Sure, they may not look very homey to us, but they're an ingenious way to deal with the terrible problem of the thousands left homeless by the earthquake, while making sure older subway models don't end up in a landfill somewhere. Altogether, the trains will accommodate roughly 1,200 people. [China News]
